摘要： A trailing ABS face, which is a surface generating positive pressure, is formed to rise from a surface facing a recording medium, which is a surface generating negative pressure, toward the recording medium and furthermore, a surface facing the element, in which a gap portion of a magnetic element is located, is formed to rise from the trailing ABS face. Thereby, the floating lift of a magnetic head can be reduced while the floating position can be stabilized and furthermore, collision of the magnetic head with a disk surface can be properly avoided.

摘要： A thin film magnetic head includes a recording and playback element, a lead conductor layer for feeding a power to the recording and playback element, an electrically conductive bump for conductively connecting the lead conductor layer to an electrode pad for external connection, and an insulating protective layer filling between the recording and playback element and the electrically conductive bump. A thermal deformation-preventing layer composed of a material having a thermal expansion coefficient smaller than that of the insulating protective layer is disposed in the insulating protective layer in such a way as to locate between a medium-facing surface and the electrically conductive bump without being exposed at the medium-facing surface. In the resulting thin film magnetic head, protrusion of the recording and playback element toward the recording medium side can be prevented without changing the configuration of the recording and playback element nor the forming material.

摘要： In a perpendicular magnetic recording head comprising a main magnetic pole layer and a return yoke layer which are laminated with a magnetic gap layer interposed therebetween, a nonmagnetic throat height determining layer and a return yoke reinforcement layer made of a magnetic material having a saturated magnetic flux density higher than that of the return yoke layer are provided on the magnetic gap layer. The nonmagnetic throat height determining layer has a front end face parallel to the medium-opposing surface at a position retracted by a desirable throat height from the medium-opposing surface. The return yoke reinforcement layer is formed directly under the return yoke layer so as to extend at least from the front end face of the nonmagnetic throat height determining layer to the upper face thereof, and is exposed at the medium-opposing surface between the magnetic gap layer and return yoke layer.

摘要： An improved magnetic head includes a slider and a thin film element, the later of which is provided on a trailing side of the slider. The slider has core layers. The surfaces of the core layers are abraded so that the thickness of an &agr; phase constituting the, surface structures of the core layers may be reduced to a very small value. In this way, even if a carbon film is directly formed on the core layers, it is still possible to ensure a desired diffusion between the carbon film and the &agr; phase, which effectively prevents the carbon film from separation (peeling) and avoiding the formation of any spot on the carbon film.

摘要： A thin film magnetic head is provided, in which the amount of protrusion in the periphery of an element portion can be reduced or a local temperature increase of electrode leads of a heating element can be prevented. The thin film magnetic head includes a playback element disposed between lower and upper shield layers, a recording element laminated on the upper shield layer, a heating element which is disposed below a coil layer and which generates heat to allow the playback element to protrude toward the recording medium side through thermal expansion, and a pair of electrode leads including overlapping regions, which are in contact with rear ends of the heating element and which overlap with the upper shield layer, and heat dissipation regions. Furthermore, connection wiring portions of the pair of electrode leads are disposed in a region sandwiched between the upper shield layer and a magnetic layer.
